2012 SSANGYONG NEW ACTYON SPORTS ECO mode

The CDPF system enters the regeneration
mode when the driving distance becomes
approx. 600 to 1,200 km (may differ by the
driving condition and driving style). Then, the
engine ECU performs the CDPF regeneration
operation. However, the driver is not informed
with this operation by any engine warning
lamp or vehicle signal, so he/she may not
detect this operation. The control logic at the
post-injection dur-ing the regeneration
process is to increase the fuel injection
volume and control the intake air volume (by
the throttle body) in order to increase the
temperature of the exhaust gas. The driver
may not feel any particular difference from the
vehicle.
Overload of CDPF (warning lamp blinking)
(3) Warning Lamp Related to CDPF
CDPF regeneration process (warning lamp NOT illuminated) ▶
If the CDPF cannot reach the regeneration temperature due to low speed driving or other
reason during the regeneration process, the soot is continuously accumulated in the CDPF.
When this condition continues and the CDPF is overloaded with soot, the engine warning
lamp blinks to inform this situation to the driver.
In order to solve this problem, drive the vehicle at a speed of approx. 80 km/h for 15 to 20
minutes to perform the CDPF regeneration process.
If the engine warning lamp on the instrument cluster blinks, the CDPF is overloaded. In this
case, perform the step 2. 1.

2) ECU Control
(1) Function
a. ECU Function
ECU receives and analyzes signals from various sensors and then modifies those signals into
permissible voltage levels and analyzes to control respective actuators.
ECU microprocessor calculates injection period and injection timing proper for engine piston
speed and crankshaft angle based on input data and stored specific map to control the engine
power and emission gas.
Output signal of the ECU microprocessor drives pressure control valve to control the rail pressure
and activates injector solenoid valve to control the fuel injection period and injection timing; so
controls various actuators in response to engine changes. Auxiliary function of ECU has adopted
to reduce emission gas, improve fuel economy and enhance safety, comforts and conveniences.
For example, there are EGR, booster pressure control, autocruise (export only) and immobilizer
and adopted CAN communication to exchange data among electrical systems (automatic T/M
and brake system) in the vehicle fluently. And Scanner can be used to diagnose vehicle status
and defectives.

water and electromagnetism and there should be no mechanical shocks.
To control the fuel volume precisely under repeated injections, high current should be applied
instantly so there is injector drive circuit in the ECU to generate necessary current during injector
drive stages.
Current control circuit divides current applying time (injection time) into full-in-current-phase and
hold-current-phase and then the injectors should work very correctly under every working
condition.
b. Control Function
Controls by operating stages
To make optimum combustion under every operating stage, ECU should calculate proper
injection volume in each stage by considering various factors.
Starting injection volume control
During initial starting, injecting fuel volume will be calculated by function of temperature and
engine cranking speed. Starting injection continues from when the ignition switch is turned to
ignition position to till the engine reaches to allowable minimum speed.
Driving mode control
If the vehicle runs normally, fuel injection volume will be calculated by accelerator pedal travel
and engine rpm and the drive map will be used to match the drivers inputs with optimum
engine power. -

This is done periodically under certain operating conditions. When the resetting is finished, the
new minimum pulse value replaces the value obtained during the previous resetting. The first MDP
value is provided by the C3I. Each resetting then allows the closed loop of the MDP to be updated
according to the deviation of the injector.
B. Detection of leaks in the cylinders
The accelerometer is also used to detect any injector which may have stuck open. The detection
principle is based on monitoring the ratio. If there is a leak in the cylinder, the accumulated fuel
self-ignites as soon as the temperature and pressure conditions are favorable (high engine
speed, high load and small leak).
This combustion is set off at about 20 degrees before TDC and before main injection.
The ratio therefore increases considerably in the detection window. It is this increase which allows
the leaks to be detected. The threshold beyond which a fault is signaled is a percentage of the
maximum possible value of the ratio.
Because of the severity of the recovery process (engine shut-down), the etection must be
extremely robust.
An increase in the ratio can be the consequence of various causes:
Pilot injection too much
Main combustion offset
Fuel leak in the cylinder -
-
-
If the ratio becomes too high, the strategy initially restricts the pilot injection flow and retards the
main injection. If the ratio remains high despite these interventions, this shows that a real leak is
present, a fault is signaled and the engine is shut down.
C. Detection of an accelerometer fault
This strategy permits the detection of a fault in the sensor or in the wiring loom connecting the
sensor to the ECU.
It is based on detection of the combustion. When the engine is idling, the detection window is set
too low for the combustion caused by the main injection. If the ratio increases, this shows that the
knock sensor is working properly, but otherwise a fault is signaled to indicate a sensor failure.
The recovery modes associated with this fault consist of inhibition of the pilot injection and
discharge through the injectors.

5) Jump Starting Procedure
Position the vehicle with the charged battery so that the jumper cables will reach from the
charged battery to the battery that requires charging.
Turn off the ignition, all the lights, and all the electrical loads in both vehicles.
Leave the hazard flasher on if jump starting where there may be other traffic and any other
lights needed for the work area.
Apply the parking brake firmly in both vehicles. 1.

Clamp one end of the first jumper cable to the positive terminal on the booster battery. Make
sure it does not touch any other metal parts.
Clamp the other end of the same cable to the positive terminal on the discharged battery.
Never connect the other end to the negative terminal of the discharged battery. 6.

Clamp one end of the second cable to the negative terminal of the booster battery.
Make the final connection to a solid engine ground, such as the engine lift bracket at least 450
millimeters (18 inches) from the discharged battery.
Start the engine of the vehicle with the good battery.
Run the engine at a moderate speed for several minutes.
Then start the engine of the vehicle with the discharged battery.
Remove the jumper cables by reversing the above sequence exactly, removing the negative
cable from the vehicle with the discharged battery first.
While removing each clamp, take care that it does not touch any other metal while the other
end remains attached. 8.

▶Volume Sensitive INT (Intermittent) Wiper
For RKSTICS without the rain sensor, perform the following operation:
Controls the wiper intermittent operation by the values from the vehicle speed and the
volume (resistance). -
Calculates and converts the Intermittent interval automatically by obtaining the IN

VOLUME when the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitive mode when turning the INT switch to
the "ON" position with the engine running or starting the engine with the INT switch
positioned to "ON".
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds ˙

Vehicle speed calculation -
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
VOLUME calculation -
The pause time of the vehicle speed sensitive INT wiper is calculated by the INT volume
(input voltage). Each level has the hysteresis. ˙
Pause time calculation -
Pause time means the duration that wipers are stopped at parking position.
Elapsed time means the duration after the wiper motor started to operate from parking
position.
The pause time is calculated by the vehicle speed and the VOLUME.
※If the pause time is below 1.0 second, the wipers operate without pause.
※If the pause time is over 1.5 seconds, the wipers operate intermittently. ˙
